Some week ago I have asked the above question and with the free time during the change of the year I can now answer it an I want to share some experiences: I found the Acer C720 Chromebook with the following technical data: -- 2 GByte RAM (soldered on board, not update-able) -- 2 core CPU, each 1.4 GHz -- display 1366x768, ~11 inch, very nicely support by Xorg VESA driver -- Wifi Atheros AR946x/AR948x, supported by ah(4) -- sound supported by snd_hda(4) -- 16 GByte SSD, can be swapped by, for example, MTS400 M.2 SSD 128GB SATA III, MLC (128 GByte) I will attach a dmesg output; The problem was: 1. It needs take apart the device to unlock the BIOS protection to be able to use a SeaBIOS for legacy boot from SSD or USB; 2. One needs some patches against -HEAD; All this is very good documented by the author of the patches, Michael Gmelin, in his blog: http://blog.grem.de/pages/c720.html Thanks to him for this work and his helping hand during my first steps with this nice device. I think, the patches should be incorporated into SVN, at the moment they are against -HEAD as of January 5th. The keyboard of the C720, in principle a normal PC105, mine with German layout QWERTZ, is a bit tricky: it has - only F-keys from F1 to F10 and they are labeled with symbols for the ChromeOS applications; - no hardware power-off (only by an ACPI key which is situated where F11 would be, i.e. right above the Backspace key, you see the risk :-) ) - no Windows key which could be used as Modifier-key in X11; - no PageUP/DOWN keys - no 'blue Fn' key for additional functions (like audio or brightnes) In his blog Michael documents as well ways to help out of this. It now runs very nicely -HEAD (still booted from an USB stick because I'm waiting for the 128 GByte SSD to swap it). I'm really surprised about the battery: lasts for 6-8 hours. Wow!!!

But the older Acer netbooks used Fn+up/down, so probably something similar can be done. Alt+up/down, maybe. When researching this machine a couple of weeks back, I saw somewhere that it was based on a similar existing PC-compatible Acer model, V3 or V5 maybe, or the ES1 series (can't find the reference again, of course). But all of those with 11.6" displays look to have older or less powerful processors, typically the Celeron N2840. The Celeron 2955 in the C720 is about 50% faster. The E3-111-P8DW has a faster CPU, but it is a third-generation N3530. Standard hard drive and socketed RAM, though.

N2840 is dual-core. They are both architecturally successsor of 'Atom' core family despite being labelled Celeron or Pentium. The brands are good for Intel to differentiate prices but useless for technical purpose. The same happens to AMD too. Acer provides model variations in CPU, RAM, storage, display, etc. according to geo markets. For example ES1-111 is only available with N2940 (another quad-core) here in Taiwan. If you can find a quad-core Baytrail model and don't mind slower single-thread performance, the E3 or ES1 series are easier to install FreeBSD I guess. Total multi-thread performance are comparable. And now prices do not differ much either, since Microsoft tax is lifted from these new cheaper models to compete with Chromebooks. -Jia-Shiun.
